How to use this product
- Ensure surfaces are clean, dry and free of loose material.

- Allow 2-3 hours to set in 2mm applications, in thicker applications and colder weather allow for longer drying times.
- Once completely set, Spakfilla Heavy Duty can be sanded to a feathered edge for a perfect finish.
- Paint with water or oil-based paints after applying an undercoat.
